2 tablespoons unsalted butter
1 pear, thinly sliced
½ cup frouncesen chopped onions
2 teaspoons lemon juice
4 slices pumpernickel bread, toasted and each slice cut into quarters
1 cup crumbled blue cheese
¼ cup white chocolate shavings
Kosher salt to taste
Black pepper to taste
Preheat the broiler on low.
In a large skillet over medium-high heat, add butter. When the butter has melted add the pear slices, onions, lemon juice, and a pinch each of salt and pepper. Cook until the pears are warmed through and soft but still hold together, about 5 minutes.
Place the toast squares onto a baking sheet. Lay a few slices of pear in a single layer on each toast square. Top with the crumbled blue cheese. Place under the broiler until the cheese begins to melt, about 1 minute. Transfer to a platter, garnish with a sprinkle of the white chocolate shavings, and serve immediately.
